' y To all whom it may concern.'

Be it known that I, GEORGE J. SCHNEIDER,

a citizen of the United States of America, residing at Detroit, in the county of Wayne have invented certain new and useful Improvements in Electrical Water-Purifying Apparatus, of which the following is a specification, reference being had therein to the accompanying draw-` ings.

T he invention relates to apparatus for electrically purifying Water, and it is the 0bject of the invention to obtain a portable instrument, simple in construction and 'thoroughly protected, so that it may be safely used by an inexperienced operator. It is a further object to prevent danger of short circuiting or the contamination ofthe water by poisonous electrolytic products.

In the drawing:

Figure 1 is a perspective view of the apparatus with thel cap `and outer casing rel moved;

Fig. 2 is a perspective view of theouter casing; and y y A `ig. 3 is a longitudinal section.v

A and B are the electrodes which are pref-v erably formed of bars of aluminum. These electrodes are secured to lan linsulator head C on which the electrical tions are mounted, and the opposite ends of the electrodes are also preferably attached to an insulator head D. E is an outer Casin orguard for protecting the electrodes, an which may be also formed of aluminum, and is provided with perforations F for the circulation ofthe Water.

The electrical conductors used for conveying the current are usually formed of copperr which under electrolytic action will wire, form a poisonous salt. To avoid any poss1- bility of electrolysis of, the'copper I have provided a construction of termina-l head which is water proof and in which the connections'l are sealed. This "is preferably member G of insulating material, which .engages a shouldered bearing H on the head C and is secured'by suitable means s .uch as the screws-I.- Within the recess :of the capv the terminals of the copper wire J are secured to binding screws .K,lwhicli-latter pass through the insulatorhead and' engage the electrodesA and B.,

Between the binding screws K is a iin L of gral with the head C. M is a lflexible water- Speeication of Letters Patent.

proof tubing, which covers the conductors and extends into the cap G. The inner end ofl this tube ispr'ovided with an enlarged head N,

tube, vpreferably formed of rubber which is pressed bythe iin L into contact with the inner face of the cap so as to form a water tight seal. Thus, where the entire instrument is immersed in' water, there will be no possibility of penetration of the water into the recess within the cap, and consequently the copper terminals are protected. With an linstrument constructed as described in use, the opera-tor merely attaches the. conductors t0 a source of current and then immerses the instrument in a vessel containing the water to be purified. lThe per- -ltrical contact.

`What I claim as my invention is 1. An apparatus for purifying water, comacedgglectrodes, a head associated with sai electrodes at one .end of the same, binding screwspassing through thefterminal head and engaging the respective electrodes first,l the contamination .of the securing the latter to the head, conductors y engaging said binding screws, anda cap devtachably engaging the head and inclosingv said binding screws, said cap being apertured 'to give passage to. said Conductors.

2. An apparatus prising a pair of spaced electrodes, an insulator head secured to said electrodes at one end of the same, conductors attached to said electrodes upon said tallic casing inclosing said electrodes, having screw-threaded engagement with saidinsulator headand a 'cap secured to said insulator 'head sealing the connection"be' Ween said electrodes and conductors.l

3. An apparatus for purifying water, comlprising spaced non-corrodible electrodes, a cad-to which said electrodes are attached,

or purifying water, come I head, a perforated meconductors connected with said electrodes.-

-upon said head, a flexible waterproof tubing surrounding said conductors, anda cap surrounding the connections between said con- A' dlCtOrS and electrodes and forming a sealigioiat wah-Said tube.

4. An apparatus for. purifying water, cornA l prising spaced non-corrodible electrodes, a head to which said electrodes are attached, terminals carried by the head respectively connected with said electrodes, a fin upon the head between the terminals, a cap inclosing said terminals having a sealing engagement with the head, and tube passing through the cap having an annular collarv Within the head, clamped between the cap and n by the engagement of the cap With the head.

5. An apparatus for purifying Water, comprising spaced electrodes, a head .to which said electrodes are attached, lteri'im'als"ear-
